摘要:
A method for thermally treating a product in order to have the product obtain the desired product properties, comprising the following steps: (a) determining the water activity value which, for carrying out the thermal treatment, is required to have the product obtain the desired properties; (b) contacting the product with water vapor, at an increased temperature and an associated saturated vapor pressure (p*), while the temperature on the surface of the product is 80-260° C.; (c) setting a vapor pressure (p) in step (b) such that p/p* is equal to the water activity value determined in step (a); and (d) maintaining for a time duration (t) the process conditions mentioned in steps (b) and (c) for obtaining the product with the desired product properties.

摘要:
An apparatus for treating food, the apparatus includes a housing having a lid, a base and a cavity defined therein. The cavity is separated into an upper chamber and lower chamber by a divider. Upper chamber is for holding food placed upon the divider. One or more steam sources provide steam to the upper and lower chambers. One or more infrared sources are position within the upper and lower chambers to directly heat the steam, the food or the divider. A pressure-controlled environment may be provided in the upper chamber. Uniformity and increased speed of heating the food is facilitated by direct heat transfer in the upper chamber and by indirect heat transfer from the conduction of heat through the divider from the lower chamber.

In accordance with the invention, a device and method for steaming and toasting food items is provided. The device is particularly suited for steaming and toasting hamburger sandwich bun heels and crowns. The device in accordance with the invention may include a steam outlet for steaming food items by impinging steam onto the food item. A conveyor moves the food item along a toasting pathway in which the food item is toasted by a heated platen extending along at least a portion of the toasting pathway.

Method and apparatus for steam-cooking food products to improve their appearance and decrease yield loss. A steam cooker includes a low-temperature, forced-convection cooking region in series with a high-temperature, steam-impingement cooking region. The food product is conveyed through both regions atop a foraminous conveyor belt. The temperature in the high-temperature cooking region is greater than the temperature in the low-temperature cooking region and less than or equal to 100° C.

摘要:
A cooking device is provided for steaming food items and transferring steamed food items from the device to a work surface. The device includes a platform for placing food items thereon mounted to a support for movement to and from food steaming and food removal positions. The food items can be transferred from the device without being individually handled by an operator. A method of steaming food items is provided using the cooking device. The food items do not need to be individually handled after they are steamed. A method of transferring steamed food items from the cooking device to a container or a work surface is also provided. The steamed food items are transferred without individual handling.

Steam-heat-only, food-preparation bowl structure and related methodology. The bowl structure includes (a) an outer bowl unit having a water well disposed adjacent its base, (b) an inner bowl unit nestable in the outer unit in a condition having its base spaced above the water well whereby water in the well does not contact the inner bowl's base, and with a generally closed, bowl-shaped void space then existing between the two units, the inner unit being constructed to receive a mixable mass of food, and (c) a controllable heater disposed within the well, operable to heat water contained therein to produce steam within the void space. The related methodology includes the steps of (a) applying mixing action to such a mass within the inner bowl unit, and while so applying, vapor-heating the mass indirectly and solely by an adjacent body of steam disposed in the void space between the units.
